AD is after the birth of christ, so we're in 2008 AD. The term AD stands for Anno Domini, Latin for 'in the year of our lord'.
It depends which ad you are talking about, but it is probably A Thousand Years by Christina Perri.
Anno Domini
Assuming that you mean 1140 AD it has been 872 years. If you're meaning BC it's been 3152 years*. 1140 years (gets us to 0 AD) + 1140 years (gets us to 1140 AD) + 872 years (gets us to 2012 AD).

50 to 60 years after the death of jesus
